1. In a vehicle slip control apparatus capable of preventing the driven wheel from slipping excessively on a road surface by controlling a torque transmitted to the driven wheel, the slip control apparatus comprising:
- torque adjusting means for adjusting a torque to be transmitted to the driven wheel;
slip detecting means for detecting a state of the slip of the driven wheel on a road surface;
slip controlling means for controlling said torque adjusting means to allow a degree of the slip of the driven wheel to become a predetermined target value in response to an output from said slip detecting means;
target value altering means for altering said target value during the slip control; and
target value instructing means for instructing a decrease or increase of the target value to said target value altering means in accordance with a requirement for the road holding capability of the driven wheel against the road surface.

Abstract
The slip control is conducted so as to cause an amount of the slip of the driven wheel to become a target value by controlling the torque to be transmitted to the driven wheel. The target value is altered during the slip control on the basis of a requirement for road holding capabilities of the driven wheel against a road surface.

16. A vehicle slip control apparatus adapted to prevent the driven wheel from slipping on pavement to an excessive degree by controlling a torque applied to the driven wheel, comprising:
-
torque adjusting means for adjusting the torque applied to the driven wheel; first rotational speed detecting means for detecting a first rotational speed of the driven wheel; second rotational speed detecting means for detecting a second rotational speed of the undriven wheel; slip ratio determining means for determining a slip ratio of the driven wheel by using a difference between the first and second rotational speeds received from said first and second rotational speed detecting means, respectively; slip controlling means for controlling said torque adjusting means so as to allow the slip ratio determined by said slip ratio determining means to become a predetermined target value; target value altering means for altering said target value while a degree of the slippage is being controlled; and target value instructing means for instructing a degree of an increase or decrease in the target value to said target value altering means in order to meet a requirement for a grip of the driven wheel against payment. - View Dependent Claims (17)
